Abstract

PURPOSE: To decrease the leak amount of refrigerant by forming the end of a vane into the shape of an arc of more than 180° degrees, and also forming a notched portion in the form of an arc of more than 180° degrees and of curvature equal to or larger than that of the end of the vane.
CONSTITUTION: A machine portion connected via a shaft 3 to an electric motor portion (not shown in the figure) and comprising a cylinder 4, a roller 5 and a vane 6 etc. is stored in a sealed casing 1. In this case the end 6a of the vane 6 is formed into the shape of an arc of more than 180° degrees. A notched portion 20 in the form of an arc of more than 180° degrees and of curvature equal to or larger than that of the end 6a of the vane is formed in the outer peripheral portion of the roller 5 interposed between the cylinder 4 and the crank portion 3c of the shaft 3 in such a manner as freely rotating. The end 6a of the vane and the notched portion 20 are fitted with each other. A sealing distance in a sliding portion comprising the end 6a of the vane and the outer peripheral portion 20 of the roller 5 is thereby extended so as to decrease the amount that refrigerant leaks from a high-pressure chamber to a low-pressure chamber.
